Abstract :
Three organotin complexes were successfully produced in the presence of sodium hydroxide by the condensation reaction of cephalexin (ligand) and tri-organotin (IV) complexes. The complexes formed were given trigonal bipyramidal geometries based on spectrum measurements. These compounds were applied as additives (0.5 percent by weight) to reduce the photodegradation of polyvinyl chloride films (40 µm thickness) when exposed to ultraviolet light at a normal temperature (max = 313 at an intensity of light = 7.75 × 10^-7 ein dm^-3 S^-1 ). The weight changes of films before and after irradiation can be applied to investigate the effectiveness of organotin (IV) complexes as photo stabilizers. After irradiation, the morphology of poly(vinyl chloride) studied by the microscope, atomic force microscopy, and scanning electron microscope was shown to be less damaged in the films containing additives. These additives are effective UV absorbers, hydrogen chloride scavengers, and peroxide quenchers.
